A low-sodium solution for gastrointestinal lavage.

Golytely is a sodium sulfate-based solution used for lavage cleansing of the colon. Although most patients and physicians prefer Golytely lavage over other methods of bowel cleansing, its highly salty taste is a drawback. This report describes the development of a modified lavage solution that has a barely perceptible salty taste. This solution was developed by removing sodium sulfate, increasing the concentration of polyethylene glycol, and making minor adjustments in the concentration of other salts. Golytely, reduced sodium sulfate Golytely (Golytely-RSS), and a balanced electrolyte solution were infused into the stomachs of normal subjects. After steady-state lavage conditions were established, the rates of fluid and electrolyte absorption were measured. Average fluid absorption rate was 791 ml/h with the balanced electrolyte solution, compared with only 63 and 45 ml/h with Golytely and Golytely-RSS, respectively. Golytely-RSS was studied at 3 infusion rates, from 0.9-1.8 L/h, and the time and volume of solution required for colon cleansing was determined; the lower infusion rate (0.9 L/h) took longer but required less solution to cleanse the colon. In conclusion, Golytely-RSS has the essential feature of Golytely; i.e., lavage is associated with negligible salt and water absorption. The less-salty taste of Golytely-RSS may make it less difficult to drink and thereby enhance patient compliance; the total volume of solution required for cleansing is less when the solution is ingested at 0.9 L/h than when the ingestion rate is 1.8 L/h.[1]
